The student will represent, solve, explain, and interpret the solution to a system of two linear equations, a linear inequality in two variables, or a system of two linear inequalities in two variables.
A.EI.2a
Create a system of two linear equations in two variables to represent a contextual situation.
A.EI.2b
Apply the properties of real numbers and/or properties of equality to solve a system of two linear equations in two variables, algebraically and graphically.
A.EI.2c
Determine whether a system of two linear equations has one solution, no solution, or an infinite number of solutions.
A.EI.2h
Verify possible solution(s) to a system of two linear equations, a linear inequality in two variable, or a system of two linear inequalities algebraically, graphically, and with technology to justify the reasonableness of the answer(s). Explain the solution method and interpret solutions for problems given in context.
